Drain jetting in Letchworth Garden City
Rods and plungers push through a blockage, which gets the water moving but often leaves the cause behind. High pressure jetting sends water along the inside of the pipe at force, scouring away grease, silt and fine roots from the walls, so the whole run is clean rather than just the blocked spot. We use it when a drain is greasy, silted up or has blocked before, and after clearing a blockage further down the line.
Why drains block in Letchworth homes
Letchworth's homes span more than a century. The original Garden City cottages near the centre date from the early 1900s, the Grange was built from 1947, Jackmans in the 1960s, and Lordship and Manor Park from the 1970s. Older drain runs often have more joints, and over time a joint can shift or let roots in. That's where repeat blockages tend to start.
The town was planned with tree lined streets and generous gardens, which is part of its character, but roots will always look for water. In the kitchen and bathroom, the usual causes are fat poured down the sink and wipes flushed down the toilet. Wipes don't break down the way toilet paper does, even when the packet says flushable.
When it keeps coming back: a camera survey
If the same drain blocks again and again, there's a reason for it. A CCTV survey puts a camera inside the pipe so we can see what's there: a displaced joint, a crack, roots or a sunken section. Then we can recommend the right fix, whether that's a patch repair, relining the pipe from the inside or replacing a section.
Drain repairs in Letchworth Garden City
Clearing a damaged drain only buys time, because waste keeps catching on the damage and the blockage comes back. Once the camera has shown what's wrong, the repair is agreed with you before any work begins, and it's one of three kinds.
Patch repair. When the damage is in one place, such as a single crack or a joint that has opened, the repair is made from inside the pipe at that spot only.
Relining. When the damage runs along the drain, a resin lining is fed through and set hard inside the old pipe, giving you a new pipe within it. In a town planned around tree lined streets and big gardens, that matters: roots get in through cracks and gaps, and a lining closes them off along its whole length.
Replacing a section. A drain that has collapsed or sunk can't be lined, so we dig down to that section and replace it.
Patch repairs and relining are done from inside the drain, so in most cases there's no trench across your lawn or drive. Every repair is guaranteed for 12 months.
Blocked toilets in Letchworth Garden City: the toilet or the drain?
When only the toilet is slow to clear, the blockage is usually in the pan or the pipe just behind it. When the bath, shower or sink is slow as well, or water is rising in the outside gully, the problem is further down in the drain, and plunging the toilet won't shift it. Either way, stop flushing until it's cleared, so the water has nowhere to back up to. We clear both, so you don't need to work out which it is before you call.

“I needed the washing machine waste replaced as part of the outside pipe has failed due to its age. Harry who carried out the work was very polite and worked in a professional manner. I will be using this company in the future and recommending them to others.”
